The Infantry Assault Badge (German: Infanterie-Sturmabzeichen) was a German military decoration awarded to Waffen-SS and Wehrmacht Heer soldiers during the Second World War. This decoration was instituted on 20 December 1939 by the Commander-in-Chief (Oberbefehlshaber) of the German Army, Generalfeldmarschall Walther von Brauchitsch. It could be awarded to members of infantry and Gebirgsjäger (mountain infantry) units that had participated in infantry assaults, with light infantry weapons, on at least three separate days of battle in the front line on or after 1 January 1940.
